Porcine Biferon-C applied together with medicinal prophylaxis in commercial pig breeding provides immunostimulation of sows and an increased viability of their piglets

Immunodeficiency of pigs resulting from the effect of various infectious and invasive pathogens, mycotoxins, heavy metals, wide usage of chemotherapeutic agents and other xenobiotics, nutritional deficiencies, deficiency of some vitamins and microelements, stresses of various etiology is one of the main causes of high morbidity in breeder herds and the offspring. In this paper, the immune status of sows and safety of suckling piglets under the effect of recombinant alpha- and gamma-interferons, the main active substances of Biferon-C preparation (the Republic of Belarus), applied in combination with conventional measures for prophylaxis with antibiotics and chemoprophylaxis are studied for the first time. It is found that the treatment of sows improves their immune status with a 2-fold increase in safety of their piglets while the offspring of untreated sows shows only a 4 % increase in viability after injections of Biferon-C. For the experiment, two groups of 10 farrow sows each were formed (Zolotaya Niva, Znamenskii Region, Tambov Province, 2017)...
